Delete branch "cosmetic-changes"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Here are the changes that have been removed from a previous PR.
BTW, it is unnecessary to put braces to every variables if you known that the variable is not concatenated with text.
Like echo "${foo}bar".
echo "$foo"; echo "bar"
There is not need to set braces expansion every time.
But that cause no issue.
@vlaborie merge?
